The YouTube videos listed above are intended to sample the many different worship styles primarily in America but also around the world. We recognize, of course, that our list does not include all religious groups and that there are a wide range of worship styles within each religious group. We hope, however, that even this limited sample provides a helpful introduction. For religious groups not allowing unofficial recordings of their services, we refer you to their official videos or websites. If you know of videos that should be added to our list, please send your suggestion to: arda@pop.psu.edu.
